[QUOTE="wilamowski3, post: 31536, member: 12343"] There was a service bulletin for oil burning that covered the L4 through 2012 model years with up to 120,000 miles. GM covered fixing them by replacing pistons with teflon coated rings. Mine is a 2013 so technically not covered. But, after forcing the issue through GM channels they paid for an oil consumption test. Mine failed the test and they replaced the pistons. In the process of repairing it they found a cracked exhaust manifold. I authorized replacing it but went back to GM. (Dealer said they would never, ever pay for it). I explained to GM that what I believe was happening is the oil that was burning was going through the engine and into the exhaust manifold resulting in excessive temps leading to the cracking. Manifold was covered by GM. Your problem getting covered is 2013 is beyond the bulletin and GM will not accept records for work done by you (even if you have them) and you're beyond the 120,000 mile point. [/QUOTE]
